How does the measurement work?

The measurement and tracking of the Heart Rate Variability with the smartphone camera while you are breathing gives an medically proven indication of how good your stress resistance is.
On a day to day basis, improve your breathing techniques and gain a much better Heart Rate Variability to avoid burnout and stress related cardiovascular diseases.

Technical issues:
We are detecting the heart rate variability with the smartphone camera. For better precision we are supporting only iPhones with 120fps and more. (SE, 5s, 6, 6 Plus, 6s, 6s Plus)
iPads are not supported due the lack of an LED
